Symptoms

When Direct Server Return (DSR) or asymmetric routing with a tunnel is deployed, the TMM process may crash if the 'cmp-hash' setting of a VLAN is set to a non-default value.

Impact

The TMM process crashes and traffic disrupted.

Conditions

There are two scenarios that may lead to this issue:
Scenario 1: DSR
- DSR is deployed.
- The 'cmp-hash' setting of a VLAN is set to a non-default value.
Scenario 2: Asymmetric routing
- The sys db variable connection.vlankeyed is set to 'disable'.
- A VLAN and a tunnel are used to handle asymmetric routing.
- The 'cmp-hash' setting of a VLAN is set to a non-default value.
